With a litany of alleged ethics controversies swirling at home, embattled Environmental Protection Agency chief Scott Pruitt took the show on the road this week, meeting with farmers in a handful of Midwestern states to talk about his policy agenda.

While Thursday evening's meeting in Lincoln, Neb., was polite, the reception in other states has not been as welcoming, especially when it comes to conversations about his ethanol policies.

Kansas says the Environmental Protection Agency has informed the state that all 105 counties in the state meet the most recent ozone standards.

The Kansas Department of Health and Environment said in a news release that EPA Administrator Scott Pruitt recently sent a letter to Gov. Sam Brownback saying this is good news for the citizens of Kansas. Pruitt's letter also encouraged the state to continue efforts to maintain air quality that meets the 2015 ground-level ozone standards.

Large livestock farms likely will have to report high levels of two types of emissions as of Wednesday, despite the Environmental Protection Agency’s last-minute effort to further delay a federal rule it’s been trying to modify for years.

The EPA tried to exempt most farms, including concentrated animal feeding operations, or CAFOs, from having to report emissions of two air pollutants — hydrogen sulfide and ammonia — that are considered hazardous.

Environmental regulations and commitments to address global warming are certainly not on terra firma. The Trump administration has vowed to ease emissions controls for power plants and to get coal miners back to work.

The Environmental Protection Agency wants to reduce the amount of fuel in our gasoline supply that’s made from plants -- fuel produced with far less carbon dioxide than petroleum or even ethanol made from corn. That has some concerned that the Trump Administration plans to pull back from supporting innovation in renewable fuels.
